Embodiment Construction

[0022]A side view of a battery pack according to the invention is shown in FIG. 1. The battery pack 1 has a two-part housing 2, which includes a bottom shell 3 and a cover shell 4. The bottom shell 3 has a floor part 5. Side walls 6.1 to 6.4 (the side wall 6.3 is obscured in this representation by the side wall 6.1) are vertically arranged at the edges of the floor part 5. The cover shell 4 has a cover part 7 and side walls 8.1 to 8.4 (the side wall 8.3 is obscured in this representation by side wall 8.1). Guide means 9 are arranged on the cover part 7. The guide means can engage into respective complementary engaging means on the electrical appliance (not shown herein).

[0023]The side walls 6.1 and 6.2 and 8.1 and 8.2 are each provided with a recess 10.1 and 10.2 or 11.1 and 11.2 that in the assembled state of the bottom shell 3 and the cover shell 4 is open towards the floor part 5. Push-buttons 12.1 and 12.2 are disposed in the recesses 11.1 and 11.2 for unlatching the latching de...

Abstract

A battery pack (1) has a housing (2) with a floor part (5) and side walls (6.1, 6.2, 6.4; 8.1, 8.2, 8.4). The side wall (6.1, 8.1) has a recess (10.1, 11.1) oriented towards the inside of the housing. A plurality of cells arranged vertical to the floor part (5) are arranged in the housing (2). An actuation means (12.1) is provided in the recess (10.1, 11.1) for actuating the latching device and unlatching the detent element (13.1) from the receptacle of the electrical appliance. The actuation means (12.1) is guided on a guide means displaceable relative to the housing (2), and a translatory axis of the actuation means (12.1) is oriented vertical to the side wall (6.1, 8.1) and parallel to the floor part (5).

Description

FIELD OF THE INVENTION[0001]The invention relates to a battery pack with a housing having a floor part and at least two side walls running parallel to each other and perpendicular to the floor part, wherein the housing has at least a recess at one of the side walls oriented towards the inside of the housing, a plurality of cells inside the housing oriented perpendicular to the floor part and a locking mechanism with at least one actuation means for unlocking the locking mechanism arranged in at least one recess.BACKGROUND OF THE INVENTION[0002]Battery packs can be used in cordless electrical appliances with chargeable storage cells for skilled workers, professionals and widely used routine use. For example, nickel-cadmium or nickel-metal hybrids battery cells are used as the storage cells, wherein several such cells are combined to form a battery pack. In the discharged state of the battery pack, the cells can be recharged using a charger device. Embodiments are well-known, in which...
